[flexcoders] How to disable a checkbox in a Datagrid Column

[b.kotireddy]

Hi guys,

I have a check box for each record in Datagrid Column. I used the
itemRenderer to create checkbox. I want to disable that column or
checkbox in that column when my user does not have permission to
uncheck or check that checkbox.  

Please help me to do this.

Thanks in advance
